So, basically they're going to be protesting at this conference being held by the American Cochlear Implant Alliance at that hotel on those dates:

To be honest, I don't see how this protest will be effective, and here's why: Registration for the conference is closed, so none of the protestors will be able to get in to the conference and they'll have to protest outside the hotel on public property. Anybody passing by on the sidewalk who sees the protestors isn't going to know there's a cochlear implant conference going on inside the hotel and/or why there are cochlear implant protestors outside this particular hotel.
The people attending the conference (audiologists, speech pathologists, doctors, educators, etc.) have each paid hundreds of dollars to attend and travel to it, and are therefore likely in favor of cochlear implants, so their minds are already made up. It's likely that many of the attendees are staying overnight at the hotel (except for any attendees who live within a short drive of the hotel) and they probably won't leave the conference during the day to go outside (except maybe for smoke breaks), so they won't even realize that there's a cochlear implant protest outside. The attendees will be too busy attending workshops, networking with other people, eating lunch, looking at exhibits, etc.
Because the cochlear implant companies who are sponsoring the conference won't see/hear the protest and won't be influenced by it (because they obviously already support cochlear implants), and because the conference attendees who have paid hundreds of dollars to be there won't see/hear the protest, and because people walking by on the sidewalk won't be aware of the connection between the protest and the conference going on inside the hotel, who are the protestors hoping to influence? Obviously the protestors don't support cochlear implants, but the presenters and people at this conference believe in cochlear implants, or else they wouldn't be there. I'm curious what the protestors think they can accomplish or demonstrate that is going to change the outcome of the conference or change the minds of the people at the conference. It's not open to the general public, and it doesn't seem that people who make policies/laws are going to be there. It's not likely to be covered by the media, so most people won't even know the protest happened.
Protests are fine, but I just don't see how this one is going to make a difference.
